ACTIVE

Recent M-class flare activity has triggered a temporary R2 radio blackout, though geomagnetic conditions remain stable at Kp 2.0. Solar activity is currently defined by impulsive X-ray events rather than widespread geomagnetic disturbance.

Expect geomagnetic conditions to remain quiet, with Kp indices hovering around 1.67 over the next 24 hours.

There is a moderate 55% probability of further C-class flares and a residual 10% chance for additional M-class events as active regions transit the solar disk.

🌌 Aurora

Aurora visibility is not expected for mid-latitudes (40-60°N) as geomagnetic activity remains below storm thresholds.

more

Observers in high-latitude regions may see standard, quiet-time auroral activity.

👁 Watch for

Monitor active region AR4549 for further flare development, as its current magnetic complexity suggests continued potential for moderate eruptions.
